what to return in onStartCommand for a service
提问by user3240944
I have been looking through the documentation and sometimes the onStartCommand()returns START_NOT_STICKY, sometimes it returns the following:
我一直在查看文档，有时会onStartCommand()返回START_NOT_STICKY，有时会返回以下内容：
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
return super.onStartCommand(intent, flags, startId);
}
I am now confused as to why some services return super.onStartCommand(intent, flags, startId);
我现在对为什么某些服务返回感到困惑 super.onStartCommand(intent, flags, startId);

It all depends on what you want. The documentationsays:
这一切都取决于你想要什么。该文件说：
For backwards compatibility, the default implementation calls onStart(Intent, int) and returns either START_STICKY or START_STICKY_COMPATIBILITY.
为了向后兼容，默认实现调用 onStart(Intent, int) 并返回 START_STICKY 或 START_STICKY_COMPATIBILITY。
So returning super.onStartCommand()is equivalent to returning START_STICKY. If you don't want the default behavior you can return another constant.
所以返回super.onStartCommand()相当于返回START_STICKY。如果您不想要默认行为，您可以返回另一个常量。

The most often used are
最常用的是
- Service.START_STICKY
- Service.START_NOT_STICKY and
- Service.START_REDELIVER_INTENT
- 服务。START_STICKY
- 服务。START_NOT_STICKY 和
- 服务。START_REDELIVER_INTENT
Service.START_STICKY will restart if the android system terminates for any reason. Service.START_NOT_STICKY will run till it has pending works. Service.START_REDELIVER_INTENT is similar to Service.START_STICKY but the original Intent is re-delivered to the onStartCommand method.
如果 android 系统因任何原因终止，Service.START_STICKY 将重新启动。Service.START_NOT_STICKY 将一直运行，直到它有待处理的工作。Service.START_REDELIVER_INTENT 与 Service.START_STICKY 类似，但原始 Intent 被重新传递给 onStartCommand 方法。
